Answer:
The answer is 6
Step-by-step explanation:
12 divided by 2 is 6. If you have a fraction of 1/2, then its half of it. 6 is half of 12. :)
Answer: 6
Explanation:
You can multiply the numerator by the numerator and the denominator by the denominator.
The numerator of 12 is 12 and denominator of 12 is 1.
[tex]\frac{12}{1} *\frac{1}{2}=\frac{12}{2}[/tex]
Simplify this fraction and you get 6 over 1 or just 6.
You can also use common sense (not really).
You probably know that 1/2 is one half. To find half of something, you would normally divide by 2. 12 divided by 2 is 6.

USE EXACT NUMBERS
y= ( )x + ( )
Answer:
The answer is y = -1/3x + 5 !
Step-by-step explanation:
If you observe the line, the y-intercept is 5, from the point in the graph (0,5). From that point, we can see that the rise over run is -1/3. Thus, y = -1/3x + 5.
John is eating out with friends, and it is his turn to pay gratuity. The bill for the food is $48.53. If he plans to tip 20%, what should the tip be?
Answer:

The value of a motorcycle decreases by 12% each year.
In a structure made of soup cans, each row has 6 more cans than the previous row.
Every year, the number of online subscribers to a service is 4 times what it was the previous year.
A doctor's office accepts 20 new patients each month.
Answer:
Question 1) Is option C: 2. (Question 2) The correct answer is 1.09 for the K12 program. Question 3) Option A: The value of a motorcycle decreases by 12% each year. (Option C) Every year, the number of online subscribers to a service is 4 times what it was the previous year.
The ratio of outputs for any two inputs that are one value apart is 4 thus option (A) is correct. The ratio of outputs for any two inputs that are two values apart is 1/8. The situation in option (3) represents the exponential function.
What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
As per the given table,
The ratio of outputs for any two inputs that are one value apart = (-1/2)/(-1/8) = 4
The ratio of outputs for any two inputs that are two values apart = (-1/8)/(-1) = 1/8
Every year, the number of online subscribers to a service is 4 times what it was the previous year's exponential function with a 4^x exponent.
Hence "The ratio of outputs for any two inputs that are one value apart is 4. The ratio of outputs for any two inputs that are two values apart is 1/8 and the third statement shows exponential function".

An orange punch is 45% juice and a mango punch is 20% juice. By combining the two, a company is making 500 L of a fruit punch that is 40% juice. How many liters of orange punch are needed for the company’s concoction? Make sure to include units. PLEASE FAST. AND SHOW WORK
Answer:
400 liters of orange punch and 100 liters of mango punch are required to create a mixture with 40% juice.
Step-by-step explanation:
Given that the orange punch has 45% juice and the mango punch has 20% juice, if you want to create a mixture of 500 liters of fruit punch that has 40% juice, to determine the percentage of punch of each fruit to be used, the following calculation must be performed:
45 x 1 + 20 x 0 = 45
45 x 0.9 + 20 x 0.1 = 42.5
45 x 0.8 + 20 x 0.2 = 40
Therefore, it takes 80% orange punch and 20% mango punch to create a mixture with 40% juice. Thus, since 500 x 0.8 equals 400, 400 liters of orange punch and 100 liters of mango punch are required to create a mixture with 40% juice.

From the list of given options, option D answers the question.
This is because, the expression above involves distributive property and only option D correctly states that.
A distributive property is:

In this case:
[tex]a = 3[/tex] [tex]b = x[/tex] and [tex]c = 2[/tex]
So:
[tex]a*(b + c) = a*b + a * c[/tex]
Substitute values for a, b and c

A savings bond currently made Jamar $2,112.64 worth of interest in 7 years. If the investment gained 5.5% annual simple interest each year, approximately how much was the bond originally bought for?
Answer:
$5487.38
Step-by-step explanation:
Given that:
Interest currently made = $2112.64
Time = 7 years
Rate of interest = 5.5% annual
To find:
The price for which the bond was originally bought ?
Solution:
We need to find nothing but the principal amount.
First of all, let us have a look at the formula for Simple Interest.
[tex]Simple\ Interest = \dfrac{PRT}{100}[/tex]
Where [tex]P[/tex] is the principal amount
[tex]R[/tex] is the Rate of Interest
[tex]T[/tex] is the time for which the investment is made
Let us put the given values in the formula:
[tex]2112.64 = \dfrac{P\times 5.5\times 7}{100}\\\Rightarrow P =\dfrac{2112.64\times 100}{5.5\times 7}\\\Rightarrow P =\dfrac{211264}{38.5} \\\Rightarrow \bold{P =\$5487.38}[/tex]

Answer:
The second answer choice

The base of the flagpole represents point B. Approximate the height of the flagpole to the nearest tenth of a foot when the angle between the ground and the top of the flagpole is:______.(a) 30° (b) 38° (c) 45°
Answer:
Step-by-step explanation:
The set up will give a right angled triangle
Given
Distance of point A from the flagpole = 25feet
If angle of elevation is 30°
Required
Height of flagpole (opposite)
Using TOA
tan theta = opp/adj
tan30° = opp/25
opp = 25tan30°
opp = 14.4feet
Hence the height of flagpole when the angle of elevation is 30° is 14.4feet
If angle of elevation is 38°
Required
Height of flagpole (opposite)
Using TOA
tan theta = opp/adj
tan38° = opp/25
opp = 25tan38°
opp = 19.53feet
Hence the height of flagpole when the angle of elevation is 38° is 19.5feet
If angle of elevation is 45°
Required
Height of flagpole (opposite)
Using TOA
tan theta = opp/adj
tan45° = opp/25
opp = 25tan45°
opp = 25feet
Hence the height of flagpole when the angle of elevation is 45° is 25feet

In a survey of 468 registered voters, 152 of them wished to see Mayor Waffleskate lose her next election. The Waffleskate campaign claims that no more than 32% of registered voters wish to see her defeated. Does the 95% confidence interval for the proportion support this claim?
a. The reasonableness of the claim cannot be determined.
b. Yes
c. No
Answer: b. Yes
Step-by-step explanation: Confidence Interval for a population proportion is calculated as:
p ± [tex]z\sqrt{\frac{p(1-p)}{n} }[/tex]
where
p is the sample proportion
n is sample size
z is z-score, in this case, as it is 95%, z-score=1.96
Calculating confidence interval:
[tex]p=\frac{152}{468}[/tex]
p = 0.3248
0.3248 ± [tex]1.96\sqrt{\frac{0.3248(0.6752)}{468} }[/tex]
0.3248 ± [tex]1.96\sqrt{0.000468}[/tex]
0.3248 ± 0.0425
Interval: 0.2823 < μ < 0.3673
The interval means we are 95% sure the true mean is between 0.2823 and 0.3673. As the campaign claims a proportion of no more than 0.32 of the voters wants to see Mayor Waffleskate defeated and the number is in the confidence interval, the claim is supported.
